BI'LGE PUMP Application filed November 6, 1928, Serial 'No.'317, 573. Renewed July 20, 1932.

My invention relates to a bilge pump and method of making same which are adapted to be actuated by hand to pump out boats and the like. The principal objects of my invention are to provide a portable pump constructed in such a manner as to eliminate the necessity of soldering the separate units together as well as the longitudinal joint of the pump barrel.

The pumps which have hitherto been made have been very expensive by reason of the fact that soldering had to be done to a great extent in uniting the separate units of the pump, and very often the pieces attached to the body of the casing were broken off thus rendering the pump useless in an emergency. A pump constructed according to my method eliminates a tremendous amount of hand labor in its manufacture and results in a pump that will endure hard usage.

With the foregoing and other objects in View, the invention consists of the novel construction hereinafter more specifically stated, and illustrated in the accompanying drawings where are shown improvements, but it is to be understood that changes, variations and modifications may be resorted to without departing from the scope of the appended claims.

In describing the invention in detail reference is had to the accompanying drawings which form a part of this specification and wherein like character of references indicates corresponding parts throughout the several views, in which- Figure 1 is a view of the valve supporting member and a view of same inserted in the lower end of the pump barrel.

Figure 2 is a sectional View in elevation of the lower end of my casing with the valve carrying member in place.

Figure 3 is a View taken on line 3-3 Figure 2.

Figure 4 is a cross sectional view in elevation of the casing of my pump, with portions thereof broken away.

Figure 5 is a cross sectional view of the spout of my pump.

Figure 6 is a detail cross sectional view of the barrel of my casing.

Figure 7 is a cross section of the casingof the body of my pump especially showing the center seam. My pump is preferably formedof this sheet steel of iron galvanized to prevent it from rusting, and this galvanizing is done either before or after the forming.

"I take a flat rectangular sheet of suitable metal of the required size to form the barrel lO'and by any suitable die or dies I shape the metal into cylindrical shape. Flanges 11 and 12 are then formed on the horizontal edges of barrel 10 and the flanges are locked together after which pressure isapplied to the interlocked flanges to secure member 10 in the cylindrical shape. Around the upper edge of member 10 is formed an inwardly rolled shaped flange 13 for the reception of a similar shaped flange on the lower edge of frustoconical shaped member 14. The upper edge of member 14 is provided with a rolled bead 15 which is rolled outwardly, but it is to be understood that the head could be rolled inwardly. If it is desired a strengthening wire may be inserted within the bead of the respective parts.

In the barrel 10 is formed an aperture which has its edge flanged at 16, and a spout 17, formed in a manner similar to the pump barrel 10 and having a rolled bead formed on its outer end, is securely fastened.

As shown by Figures 1 and 2 is acup shaped member 19 which has three legs 20 formed integral therewith so as to support the pump casing and valve from the bottom of the vessel in which it is being employed. An aperture 21 is formed in the upper surface of member 19 and valve 22 which is secured to the upper surface thereof is adapted to be seated in the aperture. Member 19 is inserted in the lower end of barrel 10 which as well as member 19 are slightly tapered. Slip collar 24 is then forced downwardly and the ears or legs 25 which are formed integral with slip collar 24 is bent under lower edge of member 19 to hold the same in lower end of barrel 10. If it is desied to remove the member 19 for repairs or any other reason ears 25 are bent outwardly and the slip collar is forced upwardl and thus releasing member 19.

What I claim is:

1. In a bilge pump comprising a tubular barrel section, a valve carrying member consisting of a tapered body portion having an annular flange formed around the lower end, a series of downwardly extending legs, and a slip collar member associated with said tubular section for removably securing the valve carrying member to the tubular mem: ber.

2. In a bilge pump comprising a tubular body member, and a cup shaped valve carrying member adapted to be removably inserted in the lower end of said tubular member, said valve carrying member provided with a flange for limiting the distance to which the member is inserted into the barrel, and means for securing the valve member in the pump barrel, said means comprising a slip collar having downwardly projecting ears.

3. In combination with a bilge pump; a valve-carrying member adapted to be removably secured in one end'of the bilge pump casing; said valve-carrying member having a flange formed near its lower end; and a slip collar for securing the valve member in place, sald sllp collar provided with ears projecting therefrom.
